Facebook blocks (bitly owned) URL shortener J.mp
J.mp the bit.ly owned URL shortener has been blocked from Facebook because “over 70% of j.mp links are spam or malicious. Facebook displays the usual link blocking page. Facebook and bit.ly have had this problem before but with bit.ly being it and it was quickly resolved. Meanwhile Facebook says “they are working with bit.ly to resolve the problem. Bitly uses data from sources such as Phishtank, Google Safe browsing, and Websense to make sure there links are safe. Bitly also brags they have a “huge stream of people and companies” flagging sites that are offending or spamish. You can still use bit.ly to post to Facebook and use your own custom URL shortened service powered by bitly as well.
[Update] J.mp is back after mass amounts of talking between bitly and Facebook.
